If you’ve spent much time creeping around inside old electronic equipment, you have undoubtedly seen numerous examples of the capacitor shown above. I really don’t have a super-strong sense of ‘how good’ Aerovox caps were as compared to their contemporaries, IE., how often they tend to need replacement, ETC,, but IIRC they tend to be more reliable than most 50’s foil caps.
“The Aerovox Research Worker” was a sort of ‘branded content’ marketing item that the company published from at least 1949 through 1958. I recently picked up a large pile of these publications, and most focus on RF and TV applications. This was the only one I could find that was audio-focused. Enjoy. CR
